Indeed.  I just did a merge of your changes with next-20090323 and it
conflicted with changes in 10 files across 4 architectures.  There has
been work on several areas that you are changing here (some of which will
make your life easier - like the percpu changes).  I suspect that at
least some of patch 1/4 could have bee split out and sent to the
appropriate maintainers.

As it is, It looks like this will need to be rebased on top of (say)
2.6.30-rc1 (at least) in order not to inflict too much pain on others.
